This is the same question as before with different numbers. It would help if you posted the real problem instead of making up other problems that were a bit like it. Anyway, in the spirit of TIMTOWTDI, here is a different solution. HTH, Rob use strict;; use warnings; my $string = "This is a sentence"; my $n = 0; $string =~ s/\s+/++$n; $n == 2 ? '-' : ' '/ge; print $string, "\n"; **OUTPUT** This is-a sentence -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/
